The second factor is the public nature of the assessment system. Annually, the school district should publish a matrix of schools and honor those schools that have performed at high levels. This provides role models for other schools to emulate. At the school and classroom levels, it provides a blueprint of those areas where teachers should focus their individual education plans (IEPs) and where grade levels or schools should focus the school’s professional development plans. The public nature of the data from the accountability system makes clear where schools are. Data should be disaggregated by race/ethnicity, socioeconomic status, English language proficiency, and disability. Performance of each subgroup of students on assessment measures makes the school community aware of which students are well served and which students are not well served by the school’s curriculum and instruction.
